On the World and Ourselves
Unde malum from where does evil come? That is the question that has plagued humankind ever since Eve, seduced by the serpent, tempted Adam to taste the forbidden fruit of the tree of knowledge of good and evil. Throughout history the awareness of good and evil has always been linked to the awareness of choice and to the freedom and responsibility to choose this is what makes us human. But the responsibility to choose is a burden that weighs heavily on our shoulders, and the temptation to hand this over to someone else be they a demagogue or a scientist who claims to trace everything back to our genes is a tempting illusion, like the paradise in which humans have at last been relieved of the moral responsibility for their actions. In the second series of their conversations Zygmunt Bauman and Stanislaw Obirek reflect on the life challenges confronted by the denizens of the fragmented, individualized society of consumers and the form taken in such a society by the fundamental aspects of the human condition – such as human responsibility for the choice between good and evil, self-formation and self-assertion, the need for recognition or the call to empathy, mutual respect, human dignity and tolerance.

Big Data, Open Data and Data Development
The world has become digital and technological advances have multiplied circuits with access to data, their processing and their diffusion. New technologies have now reached a certain maturity. Data are available to everyone, anywhere on the planet. The number of Internet users in 2014 was 2.9 billion or 41% of the world population. The need for knowledge is becoming apparent in order to understand this multitude of data. We must educate, inform and train the masses. The development of related technologies, such as the advent of the Internet, social networks, «cloud-computing» (digital factories), has increased the available volumes of data. Currently, each individual creates, consumes, uses digital information: more than 3.4 million e-mails are sent worldwide every second, or 107,000 billion annually with 14,600 e-mails per year per person, but more than 70% are spam. Billions of pieces of content are shared on social networks such as Facebook, more than 2.46 million every minute. We spend more than 4.8 hours a day on the Internet using a computer, and 2.1 hours using a mobile. Data, this new ethereal manna from heaven, is produced in real time. It comes in a continuous stream from a multitude of sources which are generally heterogeneous. This accumulation of data of all types (audio, video, files, photos, etc.) generates new activities, the aim of which is to analyze this enormous mass of information. It is then necessary to adapt and try new approaches, new methods, new knowledge and new ways of working, resulting in new properties and new challenges since SEO logic must be created and implemented. At company level, this mass of data is difficult to manage. Its interpretation is primarily a challenge. This impacts those who are there to «manipulate» the mass and requires a specific infrastructure for creation, storage, processing, analysis and recovery. The biggest challenge lies in «the valuing of data» available in quantity, diversity and access speed.

Physik des Sports
Von Krafteparallelogramm und Impulserhaltungssatz zu sportlichen Hochstleistungen und Rekorden Sport ist angewandte Physik – wer hatte das vermutet? Bei naherem Hinsehen ist dieser Gedanke jedoch gar nicht so abwegig. Gerade sind wir zweifach fasziniert, wenn wir Profisportlern bei der >Arbeit< zusehen: Mit ihren trainierten Korpern fuhren sie scheinbar perfekte Bewegungsablaufe aus. Neuartige Materialien, eine verbesserte Ausrustung und ein durch Medizin und Sportwissenschaft geleitetes Training verhelfen Sportlerinnen und Sportlern zu immer besseren Leistungen. In der Tat finden keine Weltmeisterschaften und Olympischen Spiele ohne neue Rekorde statt. Doch wie lange noch ist das moglich? Ausgehend von soliden physikalischen Betrachtungen werden die Grenzen des menschlichen Konnens ausgelotet. Mit Physik zum Erfolg: Eine grundlegende Analyse vieler mechanischer Phanomene im Sport Die Autoren nahern sich der Physik des Sports von einem interdisziplinaren Standpunkt: Beginnend mit dem Einmaleins der Mechanik, berechnen sie optimale Werte fur Sprung und Wurf, um diese Gesetze dann auf den menschlichen Korper und praktische, sportartgebundene Gegebenheiten anzuwenden. Von Ballsport uber Gerateturnen bis hin zu Aktivitaten im Wasser belegen Mathelitsch und Thaller damit eindrucksvoll die Universalitat der Naturgesetze auch auf diesem Gebiet. Die Erwahnung moderner Methoden, wie die Videoanalyse von Spielzugen und mathematische Modellierung zur Simulation von Bewegungen, rundet das Buch ab. Nach dieser Lekture werden Sie das Sportprogramm mit anderen Augen sehen. Leopold Mathelitsch war Professor am Institut fur Physik und Leiter des Fachdidaktik-Zentrums Physik an der Universitat Graz. Seit 2014 ist er im Ruhestand. Seine Forschungsschwerpunkte lagen in der theoretischen Teilchenphysik und liegen immer noch in physikdidaktischen Fragestellungen. Er ist Mitautor mehrerer Schulbucher sowie von Sachbuchern zu akustischen Themen. Sigrid Thaller ist au?erordentliche Professorin am Institut fur Sportwissenschaft und Leiterin der Doktoratsschule Sport- und Bewegungswissenschaften an der Universitat Graz. Die Themen ihrer Forschungsarbeit reichen von Modellierung menschlicher Bewegung uber Physik der Sportarten bis zum facherubergreifenden Unterricht Sport und Mathematik.
